Modified Bishop method for stability analysis of weakly sloped subgrade under centrifuge model test

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 3,   Pages 727-741 doi: 10.1007/s11709-021-0730-z

Abstract: The sliding forms of weak sloped and horizontal subgrades during the sliding process differ. In addition, the sliding form of weakly sloped subgrades exhibits considerable slippage and asymmetry. The accuracy of traditional slice methods for computing the stability safety factor of weakly sloped subgrades is insufficient for a subgrade design. In this study, a novel modified Bishop method was developed to improve the accuracy of the stability safety factor for different inclination angles. The instability mechanism of the weakly sloped subgrade was considered in the proposed method using the “influential force” and “additional force” concepts. The “additional force” reflected the weight effect of the embankment fill, whereas the “influential force” reflected the effect of the potential energy difference. Numerical simulations and experimental tests were conducted to evaluate the advantages of the proposed modified Bishop method. Compared with the traditional slice method, the error between the proposed method and the exact value is less than 32.3% in calculating the safety factor.

Consistency Guarantees for Professional Appraisal of Geotechnical Engineering Design under Market Leading

Jian-ye Zheng

Frontiers of Engineering Management 2015, Volume 2, Issue 1,   Pages 82-85 doi: 10.15302/J-FEM-2015012

Abstract: Peer review is central to the process of modern engineering. Open peer review gives the impression that decisions are arrived at in a fair and meritocratic manner with an objective, reliable, consistent process. It is responsible for identifying methodological flaws and for improving the quality. Assistance from somebody in the same discipline is valuable. Clients refer to reviewers as referees since they help to determine the fate of a design. The client sets up a hanging committee to carry out open peer review to decide whether a piece of work should be accepted, revised or rejected. Reviewers in similar specialties make up a professional group. In an open peer review refereeing a retaining and protection structure design of building foundation pit excavation, an outside expert as an assessor, might master the art of review to pay attention to guarantee consistency of processes and outcomes.

Geotechnical forensic investigation of a slope failure on silty clay soil—A case study

Mohammad Abubakar NAVEED, Zulfiqar ALI, Abdul QADIR, Umar Naveed LATIF, Saad HAMID, Umar SARWAR

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 2,   Pages 501-517 doi: 10.1007/s11709-020-0610-y

Abstract: Qila Bala Hisar is one of the noteworthy places of Peshawar, Khyber Pakhtunkhwa. The fort was constructed on a filled ground during the 18th century and it was renovated several times by the occupants ever since. Recently, due to an earthquake of magnitude 7.3, the upper part of the south-western wall of the fort collapsed. The collapse of the wall was attributed to the failure of the retained slope. This research was undertaken to characterize the slope material, study causal factors of failure and evaluate remedial strategy. The investigation involved conventional field and laboratory testing and geophysical investigation using electrical resistivity technique to evaluate the nature of stratum. Also, X-ray Diffraction and Scanning Electron Microscopy was used to study the slope material at a molecular level to evaluate the existence of swelling potential. The analysis has shown that excessive seepage of water caused by the poor maintenance of runoff and sewage drains is the causal factor triggered by the seismic event. A remedial strategy involving soil nails, micro piles and improvement of the surface drainage is recommended.
